The Rx listener abstraction allows the switch driver (e.g., mlxsw_spectrum) to register a function that is called when a packet is received (trapped) for a specific reason. Up until now, the Rx listener lookup was solely based on the trap identifier. However, when a packet is mirrored to the CPU the trap identifier merely indicates that the packet was mirrored, but not why it was mirrored. This makes it impossible for the switch driver to register different Rx listeners for different mirror reasons. Solve this by allowing the switch driver to register a Rx listener with a mirror reason and by extending the Rx listener lookup to take the mirror reason into account.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
